MARIUS OTTO, OF PARIS, FRANCE, ASSIGNOR TO AMERICAN OZONE COMPANY, OF NIAGARA NEW YORK.

FALLS, NEW YORK, A CORPORATION OF wA'rER-ozomzms APPARATUS.

Io concerned witha simple and efficient means for sterilizing the Water and removing the excess ozone therefrom. i

The object of my invention is to roduce an apparatus comprising a tank and) separator I 1n which the treatment of the Water by the ozone, aswell as the separation of the excess of ozone from the water, takes place prior to discharging the sterilized water through the dischar eipe.'

The ol owing particular advantages are present in my apparatus: First. The duration of time durin which the Water and ozone are in contact wlth each other is prolonged, so that the water is more perfectly sterillzed.

Second. A certain volume of ozonized water is maintained in the receptacle insuch a manner that before it is discharged it will have had ample time and opportunity for being Jfreed of the excess of ozone.

My inventionis illustrated in the accompanying drawings, in which- I Figure 1 is a general elevation of the entire system. Fig. 2 is a side elevation, part in section, showing particularly theK arrangement of the mixing and separating chambers. Fig. 3 is an elevation of a water-hydrant to which m im roved apparatus is especially applicablye. I?

iiei b serves as the means for drawing in the ozone.

`The particular construction of the compound water-valve and electric switch e is shown and claimed broadly in a copendin -tuous passage to the water under treatment While I have shown four such tubes, I -do not limit my invention to ap aratus in which this particular number of tu esv isemployed,

as it isobvious that any desirable number ,of tubes might be used Without departing from the spirit of my invention. For this purpose the innermost tube d, which leads the mixture of water and ozone coming from the emulsiiier b into/the next of the concentric tubes e, opens at the bottom of the said tube e. The tube e in turn leads the water and ozone upwardly and opens at the upper ortion .of the next concentric tubes he tube f leads the water and ozone downwardly again and discharges it at the bottom of the outermost tube g, which leads the water, which by this time is completely sterilized, u wardly to the discharge-pipe h. While tlib ozone and water are in contact with each other in passing throu h the concentric tubes the sterilization of t e water takes place. The water in the tube f allows the excess of ozone to escape from its surface linto the space 7c, which communicates with the out- 9ol by means of the wadding of cotton-waste port g, with a waddin acts as a kind of sa pressure of the gas accumulating in the chamer 7c will not rise too high. stated, the delivery of sterilized water takes ort g, in which 'a is inserted. This of cotton-waste, thus sired, the d1schar e-pipe 71. may be provided with a suitable vaIve operated lndependently of the compound valve and switch c.

Fig. 3 I have shown a water-postwhich is provided with my invention. The ozonety-valve, so that the.

As above place through the discharge-pipe h. If de- IOO izer a is placed in the box or case-at the top of the post and suitably connected with the source of electric current. An operating-lever for a compound electric switch and Water-valve is shown at m, and the sterilized water is discharged through the discharge-pipe h, which dischargesthe water into the basin below.

In' water-receptacles arranged as herein described the double result above referred to is obviously obtained-that is:

First.' The water which is to be sterilized and the ozonefor sterilizing the water remains mixed for as long a period as may be regarded necessary. v

Second. The water saturated with ozone is not directly delivered Jfor consumption. The excess of sterilizing-gas is separated out in the chamber 7c either during Vthe ascending movement of the water between the -tubes d and e or during its descending motion between the tubes e and f. Each time the handle rml is depressed the water-circuit is opened and the electric circuit to` the ozone-supplying means is closed, so that fresh water passes through the pre-v liminary mixer b and draws in through the conduit Zfresh-ly-ozonized air, the amount of water thus allowed to enter .the system being equal to that delivered at the discharge-pipe h. This added amount is not, however, at once delivered for consumption, but is held in reserve in the apparatus7 thereby giving it time to become completely sterilized and have all traces of the remaining ozone re- 'moved from it.

The chamber 7c instead of being supplied by an opening g for discharging the free ex cess of ozonized air may be utilized as a compression-chamber. The lozoniz'ed air not utilized which would esca e therefrom .would then have to pass througlh series of concentric tubes disposed between the tubes f and g.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. A mixing and separati/ng device for sterilizing water by ozone, com rising a series of concentrieallyarrange cylindrical compartments opening in opposite directions one into the other, the outermostof said cylindrical compartments being ifovided with a discharge-outlet and one o t ev inner compartments having a separation-chamber, and

2. An arrangement forming tank and separator for the excess of ozone in the receptacle for the sterilized water consisting in a series of concentric cylinders e, f, g, alternately closed at the bottom and to arranged around an axial tube d, throu h willich the ozonized air enters in such way t at the mixture ofwater and ozone is forced to follow an alternating descending and ascending course through the annular sp aces between said cylinders, the cuter cylinder g, forming the cover to which the tube for taking the water h, and the upper part c, of one of the cylinders closed at the top forming the separating-chamber for the escapement of the excess of ozone.
